How are lab diamond rings sourced?

Buying a lab grown diamond engagement ring is a sure fire way to ensure your engagement ring is as every bit ethical as it is beautiful - and we operate with transparency at the heart of each decision while we source the most beautiful lab grown diamonds with an emphasis on value for money. That’s why we work with only the most reputable, trusted lab diamond suppliers. We source our lab grown diamonds straight from the creators, and craft each ring in-house.

Where can I buy lab created diamond rings in the UK?

The world of lab created diamonds is still relatively untouched by the UK engagement ring market, meaning there are few retailers where you can buy lab diamond engagement rings and jewellery. Queensmith is at the forefront of understanding and retailing lab grown diamonds alongside bespoke engagement ring and jewellery services.

After learning your rough budget and an idea of what you’re after, our gemmologists will work on putting together a select range of the finest lab grown diamonds for your unique budget, before meeting with you to discuss your engagement ring or jewellery design.
